OAR FOR ICE-BOATS.

SPECIFICATIOlSf forming part of Letters Patent No. 288,801, dated November 20, 1883.

Application filed October 9, 1883. (No model.)

To all whom it may concern.-

1 Be it known that we, WILLIAM J. HENLEY and Srnnonn T. AXTELL, of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Ice-Boats, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This inventionconsists in a novel construction of an ear designed for propelling an icc heat.

The invention is fully illustrated in the an nexed drawings, wherein Figure l is a plan view of an ice-boat provided with our improved oar. Fig. 2 is a side view of said boat. Fig. 3 is an enlarged detail view of the oar, and Fig. 4 is a transverse section on line cu m in Fig. 3.

Similar letters of reference indicate corresponding parts. i

A represents an ice-boat of any suitable style and construction, mounted on runners R R, and provided with suitable oarlocks, B B.

C derotes the oar, which we form of sections a a, connected end to end by a longitudinallyyielding splice or joint consisting of a sleeve, 72, which is at one end rigidly secured to the end of one of the oar-sections,-and is provided at the opposite end with longitudinal slots 0 c, in which slide the ends of the bolts (1 d, which pass through the other oar-section fitted movably in said end of the sleeve I), said slots being of sufiicient length to allow the outer end of the car to retract a distance equal to the versed sine e of the segment, which is usually described by the oar when operated in water, as illustrated by dotted lines in Fig. 1 of the drawings.

In order to normally hold the car in its distended position, we place in the sleeve 1) an expansive spring, f, which forces the outer oar-section outward and yields to the inward pressure exerted by the confinement of the point of engagement of the extremity of the oar on the ice, as demonstrated by dotted lines in Fig. 1 of the drawings.

The extremity of the oar is provided with a socket, g, which we prefer to connect to the oar detachably, so as to admit of applying to the car interchangeably different devices for engaging the ice or paddles for operating in water, as may be desired. In the socket g is inserted at right angles to the oar a spur or spike, t, secured in position by a setscrew, a, said spike serving to obtain the requisite hold on the ice for propelling the boat.

Having described our invention, what we claim is 1. An ice-boat propelling-oar, provided at its outer end with a spur or spike for engaging with the ice, substantially as set forth.

2. An ice-boat propelling-oar, consisting of longitudinallyextensible sections and means for engaging with the ice on the end of the car, as set forth.

3. An ice-boat nopelling-oar, composed of sections joined end to end by a longitudinally- WILLIAM JOHN HENLEY. [It 8.] SPENCER TIMOTHEY AXTELL. [L. s]
